Yes, SSL bridging is nice if in fact the ISA was inspecting traffic as
you suggest.

So precisely what "inspection" is ISA doing?

As I understand it (I could be wrong), ISA bridges the connection
without actually doing anything to protect your web server.

With CP FW-1 you are able to set all sorts of parameters to ensure
"safe" http/s traffic. With ISA you need third party products.

Am I wrong?

Subject: Re: [FW-1] ISA Firewall Question

ISA has a couple of nice features. One of them is SSL termination. For 
example, if you have a web server that use SSL and is behind the
firewall, 
CP can't help you inspect traffic headed to it. With ISA, you do this:

Set the web server's external DNS entry to an IP address bound to the 
external interface of the ISA server.

Install a copy of the SSL certificate on the ISA server bound to the
above 
IP address.

Set ISA to perform SSL Bridging.

The traffic looks like this:

External SSL connection inbound to web server -> CP -> ISA external 
interface -> inbound traffic is decrypted and inspected by ISA ->
Traffic 
leaves the ISA server as a new SSL connection to the web server.

We use this feature and it works well. I think it's the one big feature 
missing from CP.

We also use ISA for controlling outbound web traffic by user and HTTP
virus 
scanning. It keeps that workload off the firewall.

Another really neat feature is that the ISA inbound "listener" ignores 
connections coming in by IP address and not the DNS name. It makes port 
scanning virtually useless because ISA just ignores the traffic since
the 
connection is by IP address.
